the release of the neural impulse consisting of a reversal of the electrical charge within the axon
chemicals found in the synaptic vesicles that when released has an effect on the next cell.
holes in the surface of the dendrites or certain cells of the muscles and glands, which are shaped to fit only certain neurotransmitters
chemical substances that mimic or enhance the effects of a neurotransmitter on the receptor sites of the next cell, increasing or decreasing the activity of that cell
chemical substances that block or reduce a cell's response to the action of other chemicals or neurotransmitters
a neurotransmitter that enables learning and memory and also triggers muscle contraction
major excitatory neurotransmitter involved in learning, memory formation, and nerves system formation
